constants (TODO)
================
constants
=========
The ``constants.py`` in the ``manimlib`` folder defines the constants
needed when running manim. Some constants are not explained here because
they are only used inside manim.
Frame and pixel shape
---------------------
.. code-block:: python
ASPECT_RATIO = 16.0 / 9.0
FRAME_HEIGHT = 8.0
FRAME_WIDTH = FRAME_HEIGHT * ASPECT_RATIO
FRAME_Y_RADIUS = FRAME_HEIGHT / 2
FRAME_X_RADIUS = FRAME_WIDTH / 2
DEFAULT_PIXEL_HEIGHT = 1080
DEFAULT_PIXEL_WIDTH = 1920
DEFAULT_FRAME_RATE = 30
Buffs
-----
.. code-block:: python
SMALL_BUFF = 0.1
MED_SMALL_BUFF = 0.25
MED_LARGE_BUFF = 0.5
LARGE_BUFF = 1
DEFAULT_MOBJECT_TO_EDGE_BUFFER = MED_LARGE_BUFF # Distance between object and edge

Run times
---------
.. code-block:: python
DEFAULT_POINTWISE_FUNCTION_RUN_TIME = 3.0
DEFAULT_WAIT_TIME = 1.0
Coordinates
-----------
manim uses three-dimensional coordinates and uses the type of ``ndarray``
.. code-block:: python
ORIGIN = np.array((0., 0., 0.))
UP = np.array((0., 1., 0.))
DOWN = np.array((0., -1., 0.))
RIGHT = np.array((1., 0., 0.))
LEFT = np.array((-1., 0., 0.))
IN = np.array((0., 0., -1.))
OUT = np.array((0., 0., 1.))
X_AXIS = np.array((1., 0., 0.))
Y_AXIS = np.array((0., 1., 0.))
Z_AXIS = np.array((0., 0., 1.))
# Useful abbreviations for diagonals
UL = UP + LEFT
UR = UP + RIGHT
DL = DOWN + LEFT
DR = DOWN + RIGHT
TOP = FRAME_Y_RADIUS * UP
BOTTOM = FRAME_Y_RADIUS * DOWN
LEFT_SIDE = FRAME_X_RADIUS * LEFT
RIGHT_SIDE = FRAME_X_RADIUS * RIGHT
Mathematical constant
---------------------
.. code-block:: python
PI = np.pi
TAU = 2 * PI
DEGREES = TAU / 360
Text

custom_default (TODO)
=====================
custom_default
==============
``directories``
---------------
- ``mirror_module_path``
(``True`` or ``False``) Whether to create a folder named the name of the
running file under the ``output`` path, and save the output (``images/``
or ``videos/``) in it.
- ``output``
Output file path, the videos will be saved in the ``videos/`` folder under it,
and the pictures will be saved in the ``images/`` folder under it.
For example, if you set ``output`` to ``"/.../manim/output"`` and
``mirror_module_path`` to ``False``, then you exported ``Scene1`` in the code
file and saved the last frame, then the final directory structure will be like:
.. code-block:: text
:emphasize-lines: 8, 10
manim/
├── manimlib/
│ ├── animation/
│ ├── ...
│ └── window.py
├── output/
│ ├── images
│ │ └── Scene1.png
│ └── videos
│ └── Scene1.mp4
├── code.py
├── custom_default.yml
└── manim.py
But if you set ``mirror_module_path`` to ``True``, the directory structure will be:
.. code-block:: text
:emphasize-lines: 7

``.jpg``, ``.png`` and ``.gif``), which will be read by ``ImageMobject``.
- ``vector_images``
The directory for storing vector images to be used in the code (including
``.svg`` and ``.xdv``), which will be read by ``SVGMobject``.
- ``temporary_storage``
The directory for storing temporarily generated cache files, including
``Tex`` cache, ``Text`` cache and storage of object points.
``tex``
-------
- ``executable``
The executable program used to compile LaTeX (``latex`` or ``xelatex -no-pdf``
is recommended)
- ``template_file``
LaTeX template used, in ``manimlib/tex_templates``

CONFIG dictionary
=================
What's CONFIG
-------------
``CONFIG`` dictionary is a feature of manim, which facilitates the inheritance
and modification of parameters between parent and child classes.
| ``CONFIG`` dictionary 's processing is in ``manimlib/utils/config_ops.py``
| It can convert the key-value pairs in the ``CONFIG`` dictionary into class attributes and values
Generally, the first line of the ``.__init__()`` method in some basic class (``Mobject``, ``Animation``,
etc.) will call this function ``digest_config(self, kwargs)`` to convert both
the ``CONFIG`` dictionary and ``kwargs`` into attributes. Then it can be accessed
directly through ``self.``, which simplifies the handling of inheritance between classes.
**An example**:
There are many class inheritance relationships in ``manimlib/mobject/geometry.py``
.. code-block:: python
# Line 699
class Polygon(VMobject):
CONFIG = {
"color": BLUE,
}
.. code-block:: python
# Line 801
class Rectangle(Polygon):
CONFIG = {
"color": WHITE,
"height": 2.0,
"width": 4.0,
"mark_paths_closed": True,
"close_new_points": True,
}
The ``Polygon`` class uses the key-value pair ``"color": BLUE`` in the ``CONFIG``
dictionary to add the attribute ``self.color``.
At the same time, the ``Rectangle`` class also contains the key ``color`` in the
``CONFIG`` dictionary, but the value is different. At this time, the priority will
modify the attribute ``self.color`` to ``WHITE``. And it also set some unique attributes
through the key-value pair ``"height": 2.0"``, etc., which is convenient for later use.
CONFIG nesting
--------------
The ``CONFIG`` dictionary supports nesting, that is, the value of the key is also
a dictionary, for example:
.. code-block:: python
class Camera(object):
CONFIG = {
# configs
}
.. code-block:: python
class Scene(object):
CONFIG = {
"window_config": {},
"camera_class": Camera,
"camera_config": {},
"file_writer_config": {},
# other configs
}
def __init__(self, **kwargs):
digest_config(self, kwargs)
# some lines
self.camera = self.camera_class(**self.camera_config)
The ``CONFIG`` dictionary of the ``Camera`` class contains many key-value pairs,
and this class needs to be instantiated in the ``Scene`` class. For more convenient
control, there is a special key-value pair in the Scene class ``"camera_config": {}``,
Its value is a dictionary, passed in as ``kwargs`` when initializing the ``Camera`` class
to modify the value of the properties of the ``Camera`` class.
So the nesting of the ``CONFIG`` dictionary **essentially** passes in the value as ``kwargs``.
Common usage
------------
When writing a class by yourself, you can add attributes or modify the attributes
of the parent class through ``CONFIG``.
The most commonly used is to modify the properties of the camera when writing a ``Scene``:
.. code-block:: python
class YourScene(Scene):
CONFIG = {
"camera_config": {
"background_color": WHITE,
},
}
For example, the above dictionary will change the background color to white, etc.

Configuration
=============
CLI flags and configuration
===========================
Command Line Interface
----------------------
To run manim, you need to enter the directory at the same level as ``manim.py``
and enter the command in the following format into terminal:
.. code-block:: sh
python manim.py <code>.py <Scene> <flags>
- ``<code>.py`` : The python file you wrote. Needs to be at the same level as ``manim.py``, otherwise you need to use an absolute path or a relative path.
- ``<Scene>`` : The scene you want to render here. If it is not written or written incorrectly, it will list all for you to choose. And if there is only one ``Scene`` in the file, this class will be rendered directly.
- ``<flags>`` : CLI flags.
Some useful flags
^^^^^^^^^^^^^^^^^
- ``-w`` to write the scene to a file.
- ``-o`` to write the scene to a file and open the result.
- ``-s`` to skip to the end and just show the final frame.
- ``-so`` will save the final frame to an image and show it.
- ``-n <number>`` to skip ahead to the ``n``\ ’th animation of a scene.
- ``-f`` to make the playback window fullscreen.
All supported flags
^^^^^^^^^^^^^^^^^^^
========================================================== ====== =================================================================================================================================================================================================
flag abbr function
========================================================== ====== =================================================================================================================================================================================================
``--help`` ``-h`` Show the help message and exit
``--write_file`` ``-w`` Render the scene as a movie file
``--skip_animations`` ``-s`` Skip to the last frame
``--low_quality`` ``-l`` Render at a low quality (for faster rendering)
``--medium_quality`` ``-m`` Render at a medium quality
``--hd`` Render at a 1080p quality
``--uhd`` Render at a 4k quality
``--full_screen`` ``-f`` Show window in full screen
``--save_pngs`` ``-g`` Save each frame as a png
``--save_as_gif`` ``-i`` Save the video as gif
``--transparent`` ``-t`` Render to a movie file with an alpha channel
``--quiet`` ``-q``
``--write_all`` ``-a`` Write all the scenes from a file
``--open`` ``-o`` Automatically open the saved file once its done
``--finder`` Show the output file in finder
``--file_name FILE_NAME`` Name for the movie or image file
``--start_at_animation_number START_AT_ANIMATION_NUMBER`` ``-n`` Start rendering not from the first animation, but from another, specified by its index. If you passin two comma separated values, e.g. "3,6", it will end the rendering at the second value.
``--resolution RESOLUTION`` ``-r`` Resolution, passed as "WxH", e.g. "1920x1080"
``--frame_rate FRAME_RATE`` Frame rate, as an integer
``--color COLOR`` ``-c`` Background color
``--leave_progress_bars`` Leave progress bars displayed in terminal
``--video_dir VIDEO_DIR`` directory to write video
========================================================== ====== =================================================================================================================================================================================================
custom_default
--------------
In order to perform more configuration (about directories, etc.) and permanently
change the default value (you don't have to add flags to the command every time),
you can modify ``custom_default.yml``. The meaning of each option is in
page :doc:`../documentation/custom_default`.
You can also use different ``custom_default.yml`` for different directories, such as
following the directory structure:
.. code-block:: text
manim/
├── manimlib/
│ ├── animation/
│ ├── ...
│ └── window.py
├── project/
│ ├── code.py
│ └── custom_default.yml
├── custom_default.yml
└── manim.py
When you enter the ``project/`` folder and run ``python ../manim.py code.py <Scene>``,
it will overwrite ``manim/custom_default.yml`` with ``custom_default.yml``
in the ``project`` folder.
